Yes, that works (see below), thank you. I already solved my problem in
plain Emacs Lisp, and example-blocks cannot really replace src-blocks,
but its good to know for the future that it (somehow) can be done.

* A
** B
    :PROPERTIES:
    :header-args: :var name=dblock-name
    :header-args+: :var prms=dblock-params
    :END:

#+begin_src emacs-lisp 
  (format "\n#+begin: %s %s\n#+end:\n" name prms)
#+end_src

#+results:
: 
: #+begin: bar
:  foo
: 
: #+end:

#+name: dblock-params
#+begin_example
foo
#+end_example


#+name: dblock-name
#+begin_example
bar
#+end_example
